[SSS01-08] Detecting spatial variations of earthquake clustering parameters via maximum weighted likelihoods estimates
Keywords:ETAS model, earthquake cluster, earthquake forecasting, weight likelihood estimator
The data analysis shows that the spatial variation of the MWLEs of each parameter shows different features between tectonic regions. Also, applying the MWLE method has the potentials for improving the forecasting performance of the space-time ETAS model in evaluating earthquake probabilities.
